<p>[QUOTE=&quot;ancientone, post: 2469066, member: 71599&quot;]Very cool specimens Randy! Looks like we collect some of the same things. I haven&#039;t taken pictures of my minerals yet but here are a few fossils.</p><p><br /></p><p>[ATTACH=full]518949[/ATTACH]</p><p><b>4&quot; Spinosaurus Tooth </b></p><p>Spinosaurus (meaning &quot;spine lizard&quot;) is a genus of theropod dinosaur which lived in what is now North Africa, from the lower Albian to Cenomanian stages of the Cretaceous period, about 106 to 93.5 million years ago. This genus was first known from Egyptian remains discovered in the 1910s and described by German paleontologist Ernst Stromer. These original remains were destroyed in World War II, but additional skull material has come to light in recent years. It is unclear whether one or two species are represented in the described fossils. The best known species is S. aegyptiacus from Egypt, although a potential second species, S. maroccanus, has been recovered from Morocco. Spinosaurus is often postulated as a piscivore, and work using oxygen isotope ratios in tooth enamel suggests that it was semiaquatic, living both on land and in water like a modern crocodilian.</p><p><br /></p><p>[ATTACH=full]518950[/ATTACH] <b>2-3/4&quot; Megalodon tooth.&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </b></p><p>Megalodon Shark Tooth Fossil from Cape Fear river basin, North Carolina.

Often called sea buds, blastoid fossils look like small hickory nuts. They originated, along with many other echinoderm classes, in the Ordovician period and reached their greatest diversity in the Mississippian subperiod of the Carboniferous period. However, some blastoids may have come from the Cambrian. Blastoids persisted until their extinction at the end of Permian, about 250 million years ago.[/QUOTE]</p><p><br /></p>
